Designed for maximum temperatures and optimum safety, the TT-280 temperature control unit can handle oil temperatures up to 480 °F/ 250 °C. This unit is dutiable for molds in the plastic and die casting industries. The closed, hot-oil circuit with integral cold-oil receiver in a large expansion tank eliminates the problem of oil cracking. The TT-280 is guaranteed to be a leak-proof system with a leak-resistant pump, even at the maximum working temperature. With its unique design and innovative technologies, this unit can be used and immediately switched off; there is no need to cool down the system. All Tool-Temp temperature control units and water chillers are fitted with the self-optimizing microprocessor controller MP-694 (pictured above.) The self-optimizing feature allows a very high regulating accuracy even at high temperatures and adheres to the set temperature independently of the consumer.
Also available as a twin unit, model TT-280/2, with two separate circuits. The dimensions of the twin unit are L 37.5" x W 25.75" x H 41.75" (L 960 x W 600 x H 1,070 mm). All other technical data are the same for the single-unit model.
INCLUDED FEATURES
|
● MP-694 microprocessor controller
● Automatic temperature control that activates alarm when the actual temp deviates 5+ °C from the set temp ● Automatic mold drain ● Switchable stages for varied heating capacities ● Connection for optional external thermocouple ● Limescale-free heat exchanger made of stainless steel |
● Highly audible alarm system
● Leak stopper- operates in pressure or vacuum mode to allow continuous production despite leakage from mold or connections ● Leak-proof high temperature pumping system with a by-pass that allows internal oil circulation if the circuit becomes blocked |
